Making EFI harness. Any hints?

[Hammered]

I sorted everything out and once I had teh engine running and everythng in its permanent location, I cut the harness at the ecm connector. I worked backward from each sensor/injector and tied them together where ever they naturally came together. I finally got down to the ECM and clipped everything at length there. You can get 16 pin WeatherPak connectors to create a break at the intake for the injectors. You can also buy bulkhead style Cannon plugs that you can mount on the firewall.



If I were upgrading my ecm to another brand, I would just repin the harness at that point to the new ecm. That would be way easier than running a new harness. Thus, mine is a permanent part of the car.
